Derive the SI unit of Joule (J) in terms of fundamental units.
Joule is a unit of work. Now by using the formula of work done W = F s(F = force and s = displacement) = Mas (a = acceleration) = Msv/t (v = velocity and t = time) =Ms s/t2 (as velocity is displacement /time) W = M s2/t2 hence the above formula is in form of its fundamental units like mass, time and length and the dimension formula of joule = ML2T-2
